To all whom it may concern:

Be it known that 1, James ROBERT TIN- NEY, a citizen of the United States, and resident of Phoenix, in the county of Maricopa and State of Arizona, have invented certam new and useful Improvements in Pumps, of which the following isa specification.

The present invention relates to pumps and more particularly to rotary pumps especially adapted for irrigation purposes.

The object of the invention is to provide a pump of this character in which the elements are so constructed, arranged and cornbined that the pump may be securely though detachably suspended in the well and Wlll deliver from the well a volume of fluid limited only b the cross section of the well casing, the uid delivered being constrained to substantially rectilinear upflow, all surging .and whirhn being eliminated, thereby to attain the big est'eiiioiency with respect not only to the maximum output with minimum construction of power but also to all other respects.

Another object is to provide a pump of this character of simple and durable construction, reliable in operation and easy and inexpensive to manufacture.

ther objects and advantages will be hereinafter more fully described and particularly pointed out in the appended claims, reference being had to the accompanying drawings forming part of this specification in whic Figure 1 is a side elevational view of one form of'my invention, a portion of the well casing being shown in section for the sake of illustration,

Fig]. 8 is a plan of the form shown in Fig ig. 9 is an elevational View, partly in section, of a modified form of my invention;

Fig. 10 is a transverse vertical section of the shell of this modified form;

Fig. 11 is a transverse horizontal section of the upper portion of the shell; and

Fig. 12 is a detail view in side elevation of a modified form of fluid impeller.

The pump comprises a shell 11, preferably of cylindrical form and of such size as to be a snug working fit in the well casing 10. The upper or delivery end of the shell is provided with means to prevent down flow of the fluid between the well casing and the shell which may consist of a rubber gasket-like struc ture 12 but which preferably embodies a plurality of inverted trusto-conical sections.

ture in a similar manner.

The shell 11 is supported in the well casing by a hanger which may be in the form of a rod 14, eccentrically disposed and having its lower end riveted to the shell 11, as at 15, and its upper end crooked as at 16 to engage the upper end of the well casing. The crooked end 16 is provided with a swiveled joint 17 to permit the outer portion to be turning as indicated in dotted lines in Figs. 1 and 2. The eccentricity of the rod may be thus utilized to ti hten the shell 11 in place in the casing. 11 the preferred form of supporting means the lower end of the supporting rod is threaded as shown at 18 and projects through a suitable opening in the shell 11 to engage the wall of the Well casing.

A shaft 24 is arranged to extend centrally of the well casing and the shell downwardly from the surface of the ground through the shell and is supported in the form of my invention shown in Figs. 1 and 2 by a spindle bearing. The spindle bearing comprises a. housing 25 carried by bracket arms 26 secured to the lower end of the shell. The housing 25 contains the Babbitt metal or other bearin metal which directly engages the lower on of the shaft.

I The shaft 24 drives the rotary element or fluid propeller 27 of the pump, the motion being communicated to the shaft by suitable gearing such as a belt and pulley 28 and 29 IQSPBQtIVGIy, driven from any suitable form of ower plant (not shown).

he rotary element 27 of the pump in all embodiments of the invention is disposed well down within the casing and in the form shown in Figs. 1 and 2 is disposed adjacent the lower end thereof. In this form the rotary element comprises a disk slitted as at 30 from the periphery of the disk inwardly for a substantial distance on a diameter as seen in Fig. 5 and then bent to form a propeller as seen in Fig. 2. The disk is-welded to the shaft as shown at 31 in Fig. 2.

A plurality of radial vanes 32 are arranged in the shell and extend from the top of the ropeller to the u per end of the ties ing. clear of the propeller that is while they are disposed so as not to lie in the path of the propeller at any time they do lie imme diately above the same. The inner ends of the vanes are preferably carried by a sleeve 33 which embraces the shaft 24 which is however free to rotate relative thereto. The longitudinal edges of the vanes are bent to form curve flanges 34 secured respectively to the sleeve and the shell in any suitable manner.

As shown in Figs. 3 and 4 the propeller 24 may be disposed approximately centrally of the shell, the length of the vanes being correspondingly shortened. The lower end of the rope ler carries a bearing collar 35 which with the tub 36 formed on the spider arms 37 constitutes an auxilia bearing. This auxiliary bearing greferab y supplements but may take the p ace of the splndle bearing. The outer ends of the spider arms are elongated and attached in any conventional manner to the interior wall of the shell.

The shaft 24 is preferably constructed in two sections, the up or section being provided with a square axial socket 38 to receive the squared end 39 of the lower section. The end 39 is' rovided witha slot 40 extending longitu inally of the shaft. A cross pin 41 is carried b the end walls of the socket 38 and exten 3 through the slot. The 1 sections are thus constrained, to each partake of the rotary movement of the other but may be moved longitudinally of each other he lower ends 0 the vanes are just.

for a distance limited by the length of the top of the well casing, an a rtured bearing plate 43 serving ,as a seat or the adjustin nut 44 which is carried by the upper end 0 the rod. Thelower end of the rod 14 extends through a smooth bored bracket 45 secured to the shell 11 and the lower extremity of the rod beneath the smooth bored bracket has a swivel connection 46 to the bell crank 47 which bell crank carries a pivoted dog 48 for engagin the well casing.

In this embodiment '0? my invention the length of the shell is equal -to its diameter, it being found that these proportions are adequate to meet the exigencies of a large number of uses. The radial vanes 32 which are carried by the shell as in the other embodiment of the invention are somewhat shorter but are of sufficient extent to effect their purpose.

As shown in detail in Fig. 12, the rotary element of the pump in this form of the invention includes a hub 49 having a spiral imeller 50 integrally formed therewith. The liub 49'is keyed, as at 51, to thedrive shaft 24. The peripheral edge of the impeller 50 is bevele ,upwardly as indicated at 51, whereby the friction surface between the impeller and the shell is minimized to eliminate the deleterious effects of handing or the like.

In operation the pump having been suspended in the well and secured in place and motion having been imparted to the ropeller, the fluid in the well will be lifte by the propeller. The propeller however in acting upon the fluid not only forces the same upwardly but also tends to impart a whirling motion to the same which reduces surging and the like in the shell. e latter tends to reduce the output of fluid by decreasing the efliciency of the pump. These tendencies of the ropeller are overcome in the present invention for the fluid delivered from the propeller is received in the spaces between the vanes which arrest such motion and constrain the fluid to substantially rectllinear upward motion therein and thereafter in the well casing and in feet throughout the entire. conduit defined by these members and any similar member that ma be connected thereto for conveying the fluld to the desired point. y i

The posit1on of the shell in the well casmg may be adjusted to suit the conditions rotary element and the shell.

messes and in any position to which the shell is adjusted the packing means carried by the uppe end thereof is operative to effect the desired seal between the shell and the upper end of the well casing.
